Smoking tube



Patented Feb. 16, 1937 UNITED STATE 'l T OFIQE 1 Claim.

This invention relates to an improved smoking tube and seeks, amongother objects, to provide a simple and attractive novelty adapted tocontain a cigarette while being smoked so that ashes or sparks cannotfall on the clothing or fly in the face, the device thus beingparticularly suitable for use by motorists.

A further object of the invention is to provide a device embodying abarrel slotted longitudinally to provide uninterrupted ventilation for alighted cigarette within the barrel, wherein the slots will be selfcleaning so that said slots will not easily become clogged. and whereinthe barrel will be formed between the slots with rows of spaced openingsto provide auxiliary ventilation.

The invention seeks, as a still further object, to provide a barrelhaving a reduced nipple at its rear end for receiving and holding acigarette centered within the barrel, wherein said nipple will serve tosnuff the cigarette when burned approximately even with the forward endof the nipple and wherein the nipple will also serve to detachablyreceive the mouthpiece of the device so that the mouthpiece will firmlysupport the barrel.

Other and incidental objects of the invention not specifically mentionedin the foregoing will appear during the course of the followingdescription and in the drawing which forms a part of my application.

Figure 1 is a perspective view of my improved smoking tube.

Figure 2 is an enlarged longitudinal sectional view taken mediallythrough the device.

Figure 3 is a transverse section on the line 33 of Figure 2.

Figure 4 is a fragmentary section showing a modified form of closure forthe barrel of the device.

In carrying the invention into effect, I provide a cylindrical barrel inwhich is preferably of bakelite and formed on the barrel at its innerend is a reduced nipple l I.

At diametric points, the barrel I0 is, as seen in Figure 2, providedwith longitudinal slots l2 which extend throughout the major portion ofthe length of the barrel. These slots will thus provide uninterruptedventilation for a lighted cigarette within the barrel and, as will beobserved, said slots are V-shaped in cross section, the wide portions ofthe slots being disposed outwardly at the outer periphery of the barrel.The slots 12 will thus tend to be self cleaning so that said slots willnot easily become clogged while,

however, ashes and sparks cannot fall through the narrow portions of theslots.

Formed in the barrel iii midway between the slots i2 are longitudinalrows of spaced openings l3, said rows being longitudinally coextensivewith the slots. These rows of openings are provided to affordventilation auxiliary to the slots for a lighted cigarette within thebarrel and, of course, the openings are of such a size that ashes andsparks cannot fall through.

At its forward end, the barrel I0 is formed with a lateral ear M andmounted thereon is a swinging closure l5 connected to the ear by a rivetl6 or the like. The closure I5 is of a diameter to overlie the forwardend of the barrel and formed on said closure is a lateral stop lug I!adapted to engage the barrel for limiting the closure in shut position.In this connection it should be observed that the closure will be moreor less tightly held by the rivet It so that the closure will notaccidentally swing open when the device is in use. Formed in the closureare spaced ventilating openings [8 like the openings 13, the openings I8being of a size to retain ashes and sparks within the barrel It].

In conjunction with the barrel I0, I also provide a mouthpiece 19 whichis formed at its forward end with a chamber 20 adapted to snugly butremovably receive the nipple ll of the barrel and leading from saidchamber is a. duct 2|.

As will now be seen, the closure 15 may be swung open and a cigarette,as conventionally shown at 22, inserted in the barrel to to engage atits inner end in the nipple H. The nipple is of a diameter to more orless snugly receive the cigarette so that, as brought out in Figure 2,the nipple will serve to support the cigarette centered within thebarrel l0. Accordingly. the mouthpiece l9 may be placed in the mouth andthe cigarette lighted after which the closure I5 may be swung shut andthe cigarette smoked, as will be appreciated, without the annoyance offalling ashes or the danger of flying sparks.

In the present instance, I have shown the inner end of the cigaretteflush with the rear end of the nipple but, as will be noted, the chamber20 of the mouthpiece I9 is of a length to permit the cigarette, as it isinserted, to be pushed through the nipple a short distance so that,after the cigarette is smoked, the mouthpiece may be rer moved when therear projecting end of the cigarette may be grasped for removing thestub from the nipple.

As the cigarette burns, the slots l-Z will provide uninterruptedventilation while the rows of openings l3 will provide ventilationauxiliary to the slots so that free combustion will be afforded. Whenthe burning part reaches the forward end of the nipple ll, however, thecigarette will be snuffed by the nipple, this being due to the fact thatthe nipple is imperforate and surrounds the rear end of the cigarettemore or less snugly to closely confine the tobacco therein and shut ofiventilation. Overheating of the mouthpiece will thus be prevented.

In Figure 4, I have shown a modified form of closure 23 which may, ifdesired, be used in lieu of the swinging closure l5. As will be noted,the lug l4 on the barrel is eliminated and the closure 23 is in the formof a cap adapted to slip over the forward end of the barrel to befrictionally held thereon, the cap being provided with openings 24 of asize to retain ashes and sparks within the barrel. Otherwise, thismodification is identical with the preferred construction and furtherdescription is accordingly believed unnecessary.

Having thus described the invention, I claim:

In a smoking tube, the combination of a onepiece barrel stepped indiameter near its rear end to provide a reduced nipple at the rear endof the barrel adapted to frictionally receive one end portion of acigarette and hold the cigarette centered within the barrel, the barrelbein formed at diametrically spaced points with narrow longitudinalv-shaped slots extending throughout the major portion of the length ofthe barrel to afiord uninterrupted ventilation for the cigarette whenlighted and being provided midway between said slots with diametricallyspaced longitudinal rows of spaced openings to afiord ventilationauxiliary to said slots, the barrel being imperforate between the slotsand said rows of openings, a mouthpiece having a chamber therein tofrictionally receive said nipple and of a length to freely accommodatethe adjacent end of the cigarette when projected through the nipple, thenipple being imperforate for snufing the cigarette and preventingoverheating of the mouthpiece, and a closure for the forward end of thebarrel.
